Ian Hafkenschiel — Founder
I’m an independent Mobile Systems Architect (C2C) focused on stabilizing and extending production mobile platforms. Most of my work involves applications that are already live: real users, uptime expectations, and multi-year lifecycles. I’m typically brought in when reliability, performance, and long-term maintainability matter more than rapid feature churn. I work best in distributed, low-ceremony environments where outcomes matter more than visible busyness. What I’m usually brought in for: • React Native performance and stability (startup time, memory, rendering, crash reduction) • Platform upgrades, SDK migrations, and dependency modernization • Architecture refactoring and long-term maintainability planning • CI/CD hardening and release discipline • Cross-platform delivery across iOS / Android / web / TV My background includes regulated and operationally sensitive systems, where data handling, access control, and reliability are non-negotiable. I recently published the book, "The Auditability Gap: Non-Reproducible Intelligence in Regulated Systems", which explores the challenges of deploying probabilistic AI in environments that require reproducibility and auditability. I operate through Invariant Engineering Group (TigerByte Studio LLC) for structured engagements when a client needs a small embedded team rather than a single engineer. Engagement preferences: • Contract / Corp-to-Corp • Fully remote • Distributed teams • Long-horizon engagements • Outcome-driven delivery I am not interested in commission-only, business ownership, or network marketing opportunities.
